Abstract

A wheel loader includes detectors and a controller. The detectors include at least an accelerator pedal angle detector that detects an accelerator displacement. The controller includes: a state judging unit that judges from a detection result provided by the detectors whether or not the wheel loader is in an excavation operation; and a torque-curve selector. The torque-curve selector selects one excavation torque curve when the wheel loader is judged to be in the excavation operation by the state judging unit, and selects one of two or more non-excavation torque curves depending on the accelerator displacement when the wheel loader is judged not to be in the excavation operation.
